Protocol gateways
Protocol gateways translate between different OT protocols, bridging the gap between legacy fieldbuses and modern industrial Ethernet.
Devices like MGates handle protocols such as Modbus RTU/TCP, PROFINET, EtherNet/IP, CANopen, IEC 61850, PROFIBUS and DNP3.
Areas of application
When legacy field devices such as PLCs, drives or sensors only support serial bus communication, a protocol gateway can ensure that these devices can communicate with SCADA systems or IIoT platforms - without the need for equipment replacement.
In systems with both fieldbus and Ethernet applications, gateways can ensure traffic segmentation and translation, for example. Modbus RTU → Modbus TCP, PROFIBUS → PROFINET or CANopen/J1939 → Modbus TCP.
Many gateways offer built-in tools such as traffic monitor, protocol diagnostics and status monitoring, simplifying troubleshooting and ensuring stable operation.
Benefits and advantages
Fast integration
Plug-and-play with web-based setup - no complex programming needed
Segmentation
Network traffic splitting improves security, stability and performance in OT architecture
Robust industrial design
Units come with DIN rail mounting, wide working ranges (typically -40°C to +75°C) and redundant power supply
